A little Expensive, however it insulates and works very well. I have used it in my shed, expecially on the ceiling easy to put up, and does the job!

Very effective thin layer foil and bubble insulation on a roll.
Makes it easy to use for our mini loft conversion and luxury storage rooms.
A tad on the expensive side but there is a fir amount on a roll.
We use it to put behind plaster board on the loft walls. Even though it is thin it is very thermally effective

I bought this for 2 purposes: to supplement cellotex board in a narrow space of 3" where i used 2" cellotex + a layer of airtec and also as a wrap over screwfixes economy pipe insulation (13mm) used on 15mm and 22mm heating pipes under floors (fully taped joints with aluminium foil). Airtec is stated to be equivalent of 55mm polystyrene! WOW! Really? From something only a few mm thick? Too good to be true? YES! I did some tests because when my heating was on the double insulated pipes felt WARM! Now with 13mm foam sleeve and 55mm polystyrene no detectable heat should escape!
So I used a digital thermometer probe just resting on top of the outer surface of the airtec:
Heating off in cold house = 11.2c
Heating fully on and hot pipes = 21.6c
Water temperature in the pipe = 52-54c
So significant heat loss through the foam sleeve and outer aitrtec wrap - a rise of 10c!
This stuff is basically bubble wrap with silvered surfaces. At Â£100 a roll i think i wasted my money and time putting it round my pipes. An email to their technical line was never answered so no aftersales service either!
How can anything so thin which is basically bubble wrap perform like 55mm polystyrene! The silver coating would reflect some heat, but there is very little radiated heat from pipes or radiators (which should really be named convectors)
In my view this product is hardly effective and therefore a waste of money. Very disappointing!
